264 Libussa is aMain beltasteroid that was discovered byC. H. F. Peters on 22 December 1886, inClinton, New York and was named afterLibussa, the legendary founder ofPrague.[3] It is classified as anS-type asteroid.
Photometric observations of this asteroid at the Organ Mesa Observatory inLas Cruces, New Mexico, in 2008 gave an asymmetrical, bimodallight curve with a period of 9.2276 ± 0.0002 hours and a brightness variation of 0.33 ± 0.03 inmagnitude.[2] Observation from theW. M. Keck Observatory show anangular size of 57 mas, which is close to the resolution limit of the instrument. The estimated maximum size of the asteroid is about 66 ± 7 km. It has an asymmetrical shape with a size ratio of more than 1.22 between the major and minor axes.[4]
Between 2005 and 2021, 264 Libussa has been observed tooccult five stars.[citation needed]
